“I have been sitting on this INCREDIBLE news for nearly a week, and I’m SO happy to finally share it with all of you . . .” That’s how Dena Carreyn started her Facebook post last week that has quickly gone viral. “So I show up at the school, and Lyla’s two current teachers are there, and they tell me the new teacher is on her way. And then they give me a present. And then this happened.”

Dena’s daughter Lyla suffers from a rare autoimmune condition that can lead to kidney failure. The reason she got so emotional in the video is because of the surprise Lyla’s new preschool teacher had for her.
